Decreasing the speed of a SATA dvd-drive

Hi,

I just got a new SATA dvd-burner which is quite loud when reading from a dvd at full speed. Therefore I'm trying to slow down the drive.

I know 3 different ways to do that under linux:

1. Using hdparm:

[root@ArchBen ~]# ls -l /dev/dvd
lrwxrwxrwx 1 root root 15 16. Mär 12:13 /dev/dvd -> /dev/cd/dvd-sr0

[root@ArchBen ~]# hdparm -E 5 /dev/cd/cdrom-sr0

/dev/cd/cdrom-sr0:
setting cdrom speed to 5

Well, as you can see, it seems to work. But the the drive is actually as fast (and loud) as before -> nothing changed.

2. Using eject:

[root@ArchBen ~]# eject -x5 /dev/cd/dvd-sr0

There is no error message, but it also doesn't work .

3. Using setcd:

[root@ArchBen setcd-1.5]# ./setcd -x 5 /dev/cd/cdrom-sr0
/dev/cd/cdrom-sr0:
  Speed set at 750 KB/s (5x)

And again, it didn't work.

So what could I try?

Drive: NEC AD-7170S
Motherboard: Gigabyte GA-965P-DS3

Thanks in advance,
honki

I think "5" isn't the best value, better try 4x or 8x.
